=SUM((G38:U38=(AC38-50))*(G38:U38<=(AC38-10)))

This shows a 16 week season (G38:U38 represents each week).
AC38 represents the player's season average. The issue is
that this player only played in 8 of the team's 16 weeks.
The average is correct, but the array is counting the 8
weeks that he didn't play as "0."

I think you want the following array-entered formula:

=SUM((G38:U38=AC38-50)*(G38:U38<=AC38-10)*(G38:U38<""))

I think you know that "array-entered" means press ctrl+shift+Enter instead
of just Enter.

I find that array-entered formulas are often difficult to maintain. And
sometimes they __appear__ to work (i.e. there is no error) when we make the
mistake of simply pressing Enter; but in fact, the result is incorrect.

For that reason, I prefer to use SUMPRODUCT for such formulas.
Normally-enter (just press Enter) the following formula:

=SUMPRODUCT((G38:U38=AC38-50)*(G38:U38<=AC38-10)*(G38:U38<""))

Also, if you are using Excel 2007 or later and you do not need Excel 2003
compatibility (e.g. to share the file with others who might have older Excel
versions), you could use COUNTIFS, to wit:

=COUNTIFS(G38:U38,"="&AC38-50,G38:U38,"<="&AC38-10,G38:U38,"<")
